Abstract (en)

The invention relates to a method of de-icing wind turbines of a wind park. At least a first wind turbine (WT1) and a second wind turbine (WT3) are assigned to the wind park (WP). The first wind turbine (WT1) produces a first electrical output power (Pout1), which exceeds a first power threshold value (PTV1). The second wind turbine (WT3) produces a second electrical output power (Pout3), which falls below a second power threshold value (PTV2). The first output power (Pout1) and the second output power (Pout3) are reported to a power controller (PC)of the wind park (WP). The power controller (PC) detects that the first electrical output (Pout1) power exceeds the first power threshold value (PTV1) and the power controller (PC) detects that the second electrical output power (Pout3) falls below the second power threshold value (PTV2). The power controller (PC) initiates a de-icing procedure being executed at the second wind turbine (WT3) until the second electrical output power (Pout3) exceeds the first threshold value (PTV1).
